Zoo Tycoon only £14.99 at CD Keys. Click here to buy! >>
Zoo Tycoon was one of the most bizarre launch titles in console history. Partly because it tried to blend casual Kinect minigames with surprisingly in-depth simulation, but mainly because it actually worked. Though zoos could never grow large enough to be truly challenging, Zoo Tycoon was rather fun if somewhat overpriced. For £14.99, though, we reckon it's definitely worth a punt, even if GAME's stock of the physical version sadly ran out over Christmas.
